But there is one more symbol, and some more mouse operations. The symbol looks like the shortcut one (curved black arrow). First we have to take one or several files or directories with mouse, and then keeping the left mouse button pressed, put it in one of the following areas:
1) Top line (2 pixels high) of any tab (whether it is active or not, whether it is on the active panel or not);
2) Line (1 pixel high) above any path field;
3) Free space alongside of tabs.

Action after the left mouse button is released depends on what objects have been dragged:
1) For files, the source tab is duplicated (each duplicate for each dragged file);
2) For directories, they are all opened in new background tabs;
3) For archives, they are also opened as directories.

So, files dragged to any of these areas cause the source tab dupliction. More, dragging directories and archives is equvalent to commands 3003 and 3004, except that the user chooses the source or target panels himself, and that tabs are opened in background.

Neither copying nor moving is performed in any case.

Questions:
1) Are these features described in totalcmd.chm and/or history.txt? If yes, where? If no, why?
2) How can they be used?
